1.12 Calculation of axle loads
Combination of tractor and mounted implement
The mounting of implements at front and rear three-point linkage of bars is never to exceed the tractor‘s
maximum permitted total load weight or the load capacity. The tractor‘s front axles are to be loaded with 20%
of the tractor‘s unloaded weight minimum.
Check, prior to the purchase of the equipment, that these condition are met by calculating the following calculations
or by weighing the tractor- equipment combination.
Determination of the total weight, the axle load and the unloaded weight as well as the required minimum balancing
The following information is required for the calculation
